Definitions

  • the Eckspanformer are here between the cutting corners and these facing ends of the U, V or arcuate Spanleitrippe.
  • the Eckspanformer are formed either as Spanformmulde, as Spanformerhebung or as a combination of a depression and a survey in the surface of the cutting body.
  • a defined chip forming is also in the area of the cutting corner, which is both during piercing and during longitudinal turning in engagement with the workpiece, given. Due to the arrangement of the Eckspanformer between the cutting corners facing the ends of the Spanleitrippe and the cutting corners, ie in a special small distance from the cutting corners, the cutting body is particularly suitable for the removal of very small oversize.
  • the angle which is formed at one of the cutting corner 5 slightly spaced kink 18 between the horizontal to this point horizontal course of the rake face 19 and the beginning here course of formed as Spanformmulde Eckspanformers 13 is designated in the case of diagonal section as the first angle W1 and is about 10 ° to 15 °.
  • the corresponding angle formed at a slightly spaced from the main cutting edge 2 kink 20 is designated as the second angle W2 and is about 7 ° to 12 ° about three quarters of the first angle W1.
  • the arcuate section 23 of the Eckspanformers 13 is divided by this bisecting line in one of the main cutting edge 2 facing first Spanformerabites 27 and the secondary cutting edge 4 facing second Spanformerabites 28.
  • Each of Spanformerabitese 27,28 extends over an angle C and D, which is at least a quarter and at most half of the angle B described by the Eckschneidkante 24, as indicated in Fig. 13a by the angle data C m i n , Cmax and Dmin, Dmax.

Abstract

L'invention concerne un appareil de coupe servant notamment au tournage longitudinal et à l'usinage par perçage et comportant une arête principale (2), prolongée des deux côtés par une arête secondaire (4), ainsi qu'un logement (10) pour les copeaux de perçage associé à l'arête principale (2) et des logements (11) pour les copeaux de tournage longitudinal associés aux arêtes secondaires (4). Le logement (10) pour les copeaux de perçage et les logements (11) pour les copeaux de tournage longitudinal se prolongent par des niveaux pour copeaux qui forment une partie des bords d'une nervure (8) de guidage de copeaux, laquelle dessine un arc dont l'ouverture est orientée vers l'arête principale (2). L'invention est caractérisée en ce qu'un moulage d'angle (13) se trouve entre les extrémités (12) de la nervure (8) de guidage de copeaux et les points d'attaque (5) formés entre l'arête principale (2) et les arêtes secondaires (4).
